Inverse Planning Optimisation

• Planner decides on required dose coverage with dose constraints for surrounding structures  Cost function algorithm

• Upper and lower dose limits are to be nominated  Target structures have both

• Planning systems allow for dose constraints to be specified  Either as a dose max, mean dose or as a %volume to receive a specified dose  Can have either a single point, a series of points or a line
